Inventor Witnesses .J r A l Attorneys 15e-'fit Flinn S. CRAMER, .a

citizen ofv ,the'nitedlStatea residing at' Junction City, in the county of Gea-ryand StateofKansas, haveinvented a new andA usefulfflYacuumGlea'ner,"of which the fol- `Thf's en'ftion .relaties to vacuumcleaners I. lof thatl adapted tfbe operated by hand,

one Qfthepbjects ofthe invention being to provide a simple -andfetiicient device of this type Wfhclmcan be jeasilyoperated and which iscomparativelf cheap to. manufacture.

With lthe foregolngand .other objects in viewxwliiclilwill appt-"zar .as the description proceeds, the invention. resides in the combination and`arrangement of parts and in the. detailsfof construction' hereinafter described and claimed,

changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without de-g` parting from the spirit ofthe invention. In the accompanying drawings, the preferred'form of the invention has been shown.

In said drawings :-,Figur.e 1 is a perspec'A ,tive view of the machine.

lai-ged view partly intransverse'section and partly. in elevation. Fig.4 3,-is an enlarged longitudinal section through the adjustable support.l Fig.l 4 is. a transverse section through a portion of the bottom o-f the casing. v u Referring to the figures by characters of ,reference A designates -a lcasing preferably otherwise secured upon oppositel dia.

side of section 2 of the casing and a rod 7 `is mounted to slide therein, one end of the rod being' connected to the center portions of thev plates 5 anddiaphragm l4 while the` other or outer. end portion of this rod is pivotallyconnected to a lever 8 fulcrumed, as at 9, upon a bracket 10 eXtendlng later- 7 ally from the casing section 2. Lever 8 constitutes one of thelhandles of the machine. been indicated at` 11 .it being understood that. Leaps. 21.

These flanges are adapted to be I 4 preferably made of sheepskin' Apackl` ing gland 6 is located at'the center of the the section 1 c-f casing'A, said handles being preferably mounted within sleeves 12 eX- tending from said sections.

j Valve casings 13 are formed upon the sec'- tions 1 and 2 adjacent the bracket 10 and the lower end of handle 11 and communicate with the interior of casing A through ports 14. lValves lf'normally close these ports. Downwardly converging .pipes 16 extend from the respective ca sings 13 and are conreen s.l or .rUNc'rmN orar, musas.

` and ig'xeaifcaiwcted eine outer side @f nected to' 'a head 17.- This head is detach ablyengaged by the tubular stem 18' vof a nozzle'. 19 and the nozzle may be of any desired-type, this being dependent upon the work to be done. Cleanout openings 20 are formed inthe lower portions of the sections 1 and 2 and are .normally closed `by screw `Valve casings tions 1 and 2 at points diametric'ally opposite the caslngs 13 and eachof these casings 22 arelsecured upon the s ec- 22 communicates with the interior4 of casing A thro-ugh' a port A23 normally closed by a valve 24. Outletpipes 25 extend from the l casing 22 and open into a coupling 26 fromv which projects a tubular outlet stem 27. A

'.bag 28--of any suitable coarse fabric is adapt- 'ed to be secured about the stem 27 by gathering the o-pen end thereof and. tying it to the stem by means of a cord or thelike. The

vbag may be supported between the handle 11 and lever 8 by, cords,

such as 'indicated at 29, said bag .being thus held ont of contact with the surface being cleaned. f j A hanger 30A-is fxedly connected to the r ar portion of casing A and-is adjustably 4ezgaged 'by a standard 31 th'elower forked end 32 of which has a'supporting wheel 33 journaled therein.

.l When it is desired touse the cleaner the standard 3.1y isfirst adjusted along thev hanger 30 sothat wheel 33 will support the handle 11 and lever 8 at any desired'angle. The lcleaner vcan thereforebe 4used convenientlv by persons of dierent heights. After the parts lhave thus been adjusted 'the dust collector or bag 28 is secured between 4handle 11 andy lever 8 and with its open end about the outlet stem 27. The machine is then reciprocated over the 4surface to be cleaned, the nozzle *19 being held close said surface. pushed forward the natural tendency of the arms of the operator is to move toward each other.` This wil1,"obvious1y, result in lever 8 being swung toward handle 11. Rod? 1 -will bel expelled through the pipe 25 communicating with said section and thence to the stem 27 and -the dustv receiver 28. lVhen the machine iy's'moved toward the operator the tendency of thefarms is 'to move apart.

This will result in lev'er 8 being swung away from the handle 11 and rod 7 will therefore pull on Athe diaphragm 4 and create a-suction through the nozzle 19 into the section 1' while the dustl laden -air previously drawn into the section 2 will be expelled through pipe 25 into the dust. receiver 28.

From the foregoing it will be apparent thatthe machine can be easily cleaned Without requiring any unnatural o r excessively tiring movements of the arms, the movement of the machine and the actuation of the diaphragm bein effected solely by reciprocatlng the mac ine over the surface to be cleaned. K

It will be apparent that bag28 can be easily removed when filled and as this bag is made of a fabric, air dischargedl thereinto will be promptly dissipated, while the dust will be retained within they bag. Should any dust collect within either of the sections of casing A, it can be easily removed by opening the cleanout openings 20.

By supporting the bag 28 from the fixed handle 1l and the movable handle 8, it will be seen that, during the operationof the pump, the bag will be thoroughly agitated, thus preventing dust therein from becoming caked on the inner surface of the bag and interfering with the escape of air through the fabric.

The machine herein described is Very simple in construction and is easy to operate and is advantageous because of its simplicity and consequent. cheapness.

A vacuum cleanerincluding a pump, an outlet stem extending therefrom, a handle fixed relative to the pump, an operating handle movably connted thereto, and a fabric dust receiver secured about the outlet stern and to the handles, the movable handle constituting means for agit-ating the receiver during the discharge thereinto from the pump.

lIn testimony that I claim the foregoing as my' own, I have hereto affixed my signature in the presence of two witnesses.
